The RAM is 2MB * 32 70ns but the manual only talks about *36 RAM. Is this a big difference? My CPU is a 3 volt CPU. I thought it would at least post at 3.3v ? (checked this - it is 3.3v so it should be fine.) Are you saying the ram sticks are 2Mb each ? Only Macs can generally use those. They need …

Rebuilt 90% of a PCChips M577 mobo. Had missing caps, coils, RTC coin holder, missing AT P8+P9 connector, floppy and LPT headers. Sadly no dice: - ATX power doesn't work (won't turn on) - AT power works but no POST - CPU heats up (P233MMX) If anyone has any ideas what to do next, please tell me. …

Personally I like most older Intel boards but hate Intels use of Pheonix limited BIOS, the boards are generally made very well but the BIOS are designed for non techies and have just basic functions. Like buying a good HD TV but only getting one input. Just my opinion.....

My work around is to use an External 3.5" usb floppy and put a 1.2Mb 5.25" in the case. Yes have tried some bios mods back years ago but they never worked proper. As you stated the board may be designed to not support a second floppy even if the chipset and BIOS mod does. All I know is that pins 10, …

Dx4-100 is not a "speed demon", runs at 33Mhz bus like DX2-66 but does have more CPU power. 1: A DX4-100 would be the better choice over Dx2-66 if you have one. 2: If your board supports 3.3 -3.45v then a regular Intel DX4-100 will work fine (the Intel spec calls for 3.3V +/- 0.3v) so 3.45 is OK …

Spent the day in the way back machine grabbing some CT sound card jumper pages (originals, not from TH99). After editing will zip them up and add to Vogons library as a small reference library.

Yes it is possible it does not like double sided or "double banked" DIMMS, have seen that issue before where most double sided are actually also double banked. Some older motherboards come to mind that would accept 2 or 4 single sided but only one or two if double sided.
